The Concept And Process Of Rolling Mill

The Concept And Process Of Rolling Mill

Steel is widely used in our daily lives and holds a critical position in the national economy and most of the steel products we need are produced by rolling mills. The rolling process plays an important role as the final link of the steel-making process in modern steel enterprises.

Steel rolling, as its name, is a process of shaping the steel billet with rollers. And the rolling mill is what you need to get the job done. The complete rolling production process contains a series of different rolling techniques and it can be complicated. However, despite all those various requirements, the basic production process always contains the following procedures: reheating the steel billet and further treatments, rolling process, and the final finishing rolling process.

When the billets arrive, they need to be treated with chemicals like acids to remove the oxidation film and the obvious defects on the surface must be removed too. Then the billets will be reheated to a certain temperature to be ready for the coming rolling process. The rolling process is the core of this whole production, the billets will be rolled into different shapes and the rolling technique is crucial for the quality of the final product. It must meet the requirements from three different aspects: the product’s geometry dimension accuracy, internal organization, and performance, and clean and smooth surface. 

After all these processes, the product still has a complicated finishing rolling process. As a guarantee of the product, the finishing process can be different for the various requirements and standards. After the cooling, straightening, heat treatment, and other certain process procedures, the final product will meet all those customized requirements.

The Development Of The Steel Industry In China

The Development Of The Steel Industry In China

The development of the steel industry in China closely relies on other industries and shares mutual encouragement with them. Other industries like manufacturing, construction, and transportation have had higher demands for the quantity, variety, and quality of steel materials while they are looking for a leap forward. To meet their requirements, steel enterprises got to have a positive attitude and must seek an opportunity to develop their products like non-quenched and tempered steel, silicon steel, structural steel with fine mechanical properties, and other various sheets of steel applied to different industries to provide low-cost, environment-friendly materials with high-standard performances and lead their way in the rapid development.

In order to develop cutting-edge products, new treatment processes, equipment and techniques are essential. Domestic scientists and engineers have made some major breakthroughs in the new-generation automotive steel, flexible retreat technology for cold rolling, and advanced coating techniques and products. These achievements have boosted the development of revolutionary products and China’s national economy. As a crucial premise and foundation, experiment research can lead to a new process and technique innovation. Hence, strengthening the construction of research institutes and setting up its own hardware, software technology, and product development platform is critical while establishing a combination system of production and research technology innovation. The application of new techniques, new steel technology, and new steel products are just down the road.

With the global competition in the steel business growing fiercely, the market has got higher and stricter requirements for the quality and quantity of its product. The traditional rolling force calculation formula will fade and be replaced by a more ideal design method with higher accuracy -- mathematical models. It is incredibly difficult to analyze the rolling process with all kinds of factors influencing the whole procedure. The application of mathematical models like neural networks can deal with this problem. They can predict accuracy and improve the level of production control by quantitatively and qualitatively optimizing the production process to provide low-cost optimization strategies for the steel industry.

As an upcoming technology, the soft computation was applied to optimize the design of the rolling system. To solve the uncertainty and ambiguity in practical problems, the combination of human knowledge and solution methodology comes in handy, including evolutionary computation, fuzzy logic, neural computation, and probability computation.
